For Tottenham at the moment every game is a test for their injury-stricken defence and although Aston Villa may be without Gabriel Agbonlahor, nursing a groin strain, Gérard Houllier's successful resurrection of Emile Heskey could be a major factor today. Heskey will be seeking a third goal in successive matches, as opposed to successive seasons, while Spurs will hope that Rafael van der Vaart again gives them the drive which did for Twente in the Champions League in midweek. Richard Dunne is fit to return to Villa's back four if Houllier feels he needs him. David Lacey
